Pipe Flow Calculations Forum

Try with gas pressure drop calculator. It will work ok for your problem.

Hi,
Yes. That formula is ideal for your problem.
You are also free to download and try natural gas calculator that will help you on the calculation.

If you give me actual flow rate or burner power I can help you on calculation.

Bernoulli equation calculator is now available. Go to Bernoulli equation calculator Bernoulli equation is the most important equation for engineering analysis of flow problems. Most practical tasks are resolved by direct implementation of Bernoulli equation with its corresponding condition - continu...

Venturi tube and nozzle calculators are available on pipeflowcalculations.net web site that works like web application without the need to install and use plug-in. You can find calculators at: Venturi tube and Nozzle calculator Tell me what do you think about them using contact page on the same web ...

Top three calculators are now available as web application, meaning that on user side, nothing is required else but modern web browser, Internet connection and decent PC or mobile device. Pressure drop calculator, pipe diameter calculator, orifice flow calculator are now available on pipeflowcalcula...

I think so. Yet, as I said I haven't got back confirmation of the derivation that you used also, but all calculation results are very close to the conclusion that you made. 1.35 m is about 13.5 kPa, so as you have +/- 50 kPa that should be with solid reserve, which I think is ok and should be accept...

Hello and thanks for nice words about web site, as indeed it will be up for long time, I can guarantee that. Is the bladder connected to vessel all of the time? You are right that flow is not at constant rate and flow rate will be changing during pressure change. With discharge calculator, you can c...

Even if the system is closed and for example you have 50 m height difference, pressure on the lowest point will have at least that 50 m water pressure.

You might have that pressure due to hydrostatic pressure. What is elevation difference off the system?

Without knowing the K of valve you can't tell the flow rate even using gas discharge calculator. If you fully open valve you can use K for it from manufacturers datasheet.
